In arguments over the relative safeness of the world it is often pointed out that relatively few people have died recently in terrorist attacks, but as N. N. Taleb points out, the distribution of deaths by terrorist attacks is a fat tailed one: the current average does not preclude much higher future numbers. Such devices as this in the hands of such actors as NK give us more concrete feelings for the real risks involved. More focus needs to be paid to these sorts of risks, we will be lucky to live out our lives without a major nuclear terrorism event.
